C++ DLL注册

今天项目中需要用C++实现对几个DLL文件的注册，查了许多资料，总结如下：

 #include <SHLWAPI.H>
 #pragma region DLL 注册与反注册 add by whl
 #pragma comment(lib, "Shlwapi.lib")
 bool RegistryDll(CString& szDllPath)
 {
     if (!(PathFileExists(szDllPath) && (!PathIsDirectory(szDllPath))))
     {
         return FALSE;
     }
     LRESULT (CALLBACK* lpDllEntryPoint)();
     HINSTANCE hLib = LoadLibrary(szDllPath);
     if (hLib < (HINSTANCE)HINSTANCE_ERROR)
         return FALSE;
     (FARPROC&)lpDllEntryPoint = GetProcAddress(hLib, "DllRegisterServer");
     BOOL bRet = FALSE;
     if (lpDllEntryPoint != NULL)
     {
         HRESULT hr = (*lpDllEntryPoint)();
         bRet = SUCCEEDED(hr);   

     }
     FreeLibrary(hLib);
     return bRet;
 }   

 //UnRegistryDll用来反注册DLL，参数是DLL的全路径，返回值代表注册成功或者失败（TRUE为成功）。
 bool UnRegistryDll(CString& szDllPath)
 {
     if (!(PathFileExists(szDllPath) && (!PathIsDirectory(szDllPath))))
     {
         return FALSE;
     }
     LRESULT (CALLBACK* lpDllEntryPoint)();
     HINSTANCE hLib = LoadLibrary(szDllPath);
     if (hLib < (HINSTANCE)HINSTANCE_ERROR)
         return FALSE;
     (FARPROC&)lpDllEntryPoint = GetProcAddress(hLib, "DllUnregisterServer");
     BOOL bRet = FALSE;
     if (lpDllEntryPoint != NULL)
     {
         HRESULT hr = (*lpDllEntryPoint)();
         bRet = SUCCEEDED(hr);   

     }
     FreeLibrary(hLib);
     return bRet;
 }
 #pragma endregion

 #pragma region DLL 注册
     WCHAR exeFullPath[MAX_PATH]; // Full path
     GetModuleFileName(NULL,exeFullPath,MAX_PATH);

     USES_CONVERSION;
     CString str2;
     str2.Format(L"%s",exeFullPath);
     std::string str1 = W2A(str2.GetBuffer());
     str2.ReleaseBuffer();
     int pos = str1.find_last_of('\\',str1.length()-);
     std::string LibPath = str1.substr(, pos);
     std::string CPIHelperdllPath = LibPath + "\\Plugins\\1.dll";
     std::string FFSClientdllPath = LibPath + "\\2.dll";
     std::string FWPluginHelperdllPath = LibPath + "\\3.dll";

     CString CCPIHelperdllPath(CPIHelperdllPath.c_str());
     CString CFFSClientdllPath(FFSClientdllPath.c_str());
     CString CFWPluginHelperdllPath(FWPluginHelperdllPath.c_str());

     BOOL tag1 = RegistryDll(CCPIHelperdllPath);
     BOOL tag2 = RegistryDll(CFFSClientdllPath);
     BOOL tag3 = RegistryDll(CFWPluginHelperdllPath);

     if (tag1 && tag2 && tag3)
     {
         ico_RegisterDLL.SetIcon(hIconOk);
     }
     else
     {
         ico_RegisterDLL.SetIcon(hIconNo);
     }
 #pragma endregion

实现过程中遇到的问题：

1、CString与string的转换
